Qingjiao rousi (pepper and pork stir-fry) — origin & theories

Verification highlight popular claim → verdict → evidence

Some say the dish began in Fujian; others count it as Sichuan cooking, or as a Cantonese-style dish, which is how it is mostly cooked today, with more savouriness than heat and seasonings such as oyster sauce. No primary source settles which region it belongs to. Its date is just as open. The qingjiao at its heart is a sweet pepper, a variety of Capsicum with almost no heat, native to Central and South America and said to have been brought to China by Europeans at the end of the Ming dynasty, so the stir-fry can be no older than that. Hot chili peppers were known in China by 1591, when Gao Lian's Zunsheng bajian listed them among ornamental flowers, but when the sweet pepper began to be grown there, and when the dish first appears in writing, have not yet been traced. Key sources: Gao Lian, Zunsheng bajian (preface dated 1591); Brian R. Dott, The Chile Pepper in China (2020).

The three gates

Ingredient-supply gate

The bell pepper (sweet capsicum) is a New World nightshade; its arrival in China no earlier than the late Ming sets the earliest possible date. Limiting ingredient.

Cooking-technique gate

Fine-sliced pork and pepper stir-fried over high heat in a wok (chao).

Venue gate

A household and everyday-restaurant staple that spread widely.

Overview

When and where it took shape

Qingjiao rousi is green pepper (qingjiao) and pork, both cut into thin slivers and stir-fried fast over a hard wok flame. It spread as an everyday home and canteen dish, and today it is one of the standards of Chinese cooking.

The star of the plate is the green pepper, which carries almost no heat. It is a variety of the chile pepper (lajiao), also known as tianjiao or caijiao. Its home is Central and South America, and the fruit that Europeans carried eastward is said to have reached China toward the end of the Ming dynasty. A stir-fry built around the green pepper could take form only after that.

How we know

Which region qingjiao rousi belongs to is, in truth, unsettled.

It is often taken for a Sichuan dish, yet the mainstream form today is closer to the Cantonese style, leaning on savory depth over heat with oyster sauce and the like. Beyond that, some trace it to a Fujian dish of slivered stir-fried pork. Little primary evidence stands behind the Fujian-origin claim. The regional attribution sits this way, several accounts side by side, none of them settled.

The era of its making is no clearer. The green pepper is a fruit of Central and South America, and it is said to have come to China toward the end of the Ming dynasty.

The regional lineage remains a matter of several accounts, and the date of its making is not settled either. A story turning on a single fruit carried over from the Americas: that is the parentage of the plate called qingjiao rousi.
